To all whom it may concern:

Be it known that I, Roemrr L. CUZEN, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Phonograph- Lamp Attachments, of which the following is a specification.

This invention relates to phonographs and it is the principal object of the invention to provide a novel lamp attachment for the sound box thereof whereby the light rays emitted by the lamp will be projected onto the first or start of the sound recording grooves occurring on a record, thus, enabling the user to accurately position the sound box when starting the machine.

Among other aims and objects of the invention may be recited, the provision of an attachment of the character mentioned with.

a view to compactness, and in which the number of parts are few, the construction simple, the cost of production small, and eiiiciency and operation high.

The improvements in the details and ar- Fig. 2 is a vertical section taken through,

the tone arm showing the arrangement of the attachment thereon; and

Fig. '3 is a vertical longitudinal section taken through the lamp attachment.

Having more particular reference to the drawings, T represents the tone arm of the phonograph having the usual sound box S pivotally supported thereon as at 1).

With more particular reference to the present improvements, the attachment 'includes a substantially U-shaped bracket 1 preferably formed of spring metal 'and adapted to be arranged about the lower portion of the tone arm T, as shown in the Fig. 1. A screw threaded electric lamp socket 2 is carried by the U-shaped bracket 1, the said socket being provided with a base 4 in which the usual contact terminal Specification of Letters Patent. Pat gntgd Jnn 5 is arranged, whereby one connection may be made with the plug of an electric lamp 6 which is turned into engagement with the said socket. In this connection, it is to be noted that the incandescent lamj) and its respective socket are arranged at such an angle when positioned upon the under side of the tone arm T as to cause the projection of the light rays diagonally downward to a point adjacent the needle of the sound boX S, thus enabling the user to easily discern the first or start of the sound recording grooves occuring on a record, in order that the needle of the said box may be accurately engaged or placed therein.

Acap 7 is arranged over the open rear end of the screw threaded lamp socket 2 and is provided with anopening through which an electrical conductor 8 is passed into engagement with the contact terminal 5. A second electrical conductor 8 is also provided and extends into engagement with a contact terminal 9 arranged upon the under side of a switch arm 10 preferably formed of spring metal which is secured to the underside of a split insulating band 3 bracket 1 with the socket 2 and has a portion thereof arranged adjacent one side of the bracket 1. Thus, by engaging that portion of the switch arm as adjacent the bracket with the same, a circuit will be closed through the electrical conductors 8 and 8 and the incandescent lamp 6, thereby lighting the same. it will be readily understood, that but one hand will be required to properly place the needle of the sound box S and close the circuit through the incandescent lamp 6; one finger of the users hand being extended into engagement with the said switch arm 10 in order that the same may be moved into engagement with the adjacent side of the bracket 1. Just as soon as the sound box needle is properly positioned and the hand is released from the tone'arm, the circuit through the electrical conductors and the lamp 6 will be broken, due to the inherent resiliency of the circuit closing arm 10.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claim, I consider within thespirit of my invention.

I claim z- An attachment of the character describedincluding an electric lamp socket, an indiametrically opposite the bracket and havsulating band secured thereto, a substaning its opposite terminal extended vertically 10 v tially U-shaped spring bracket attachable" in proximity to andniovable into contact to the tone'arm of a phonograph and having With one of the arms of the U-shaped the Web-porti0n secured to the socket, a lamp' bracket.
